Description

Technical Field

[0002] With the rapid development of Artificial Intelligence (AI) and Augmented Reality (AR) technologies, the smart glasses market is experiencing a consumer upgrade. Simple AI functionality is no longer sufficient to meet users' comprehensive expectations for smart glasses; the deep integration of AI and AR is an inevitable trend for the future development of smart glasses. However, AI computing consumes a lot of power, requiring frequent charging. Therefore, users need to carry power banks when out and about to recharge, which increases the burden on users, especially in certain scenarios such as cycling and outdoor activities.

[0003] To address this issue, some have proposed installing a solar panel on the AR glasses case to charge the glasses. To protect the solar panel from scratches, a layer of transparent glass is typically placed over its surface. However, this transparent glass reduces the transmittance of ambient light, thus affecting the solar panel's charging efficiency and increasing the charging time of the AR glasses.

Figure 4 This is a partially enlarged view of the anti-reflective structure in a rechargeable eyeglass case provided in an embodiment of this utility model; Figure 5 This is a partially enlarged view of the antireflective structure in another rechargeable eyeglass case provided by this utility model embodiment, for reference. Figures 1-5 This utility model provides a rechargeable eyeglass case, including: a first housing 1 and a second housing 2; the first housing 1 and the second housing 2 are movably connected by a connecting part 3; a solar panel 4 is disposed on the side of the first housing 1 opposite to the second housing 2; a transparent protective layer 5 is disposed on the side of the solar panel 4 opposite to the first housing 1; an anti-reflection structure 6 is disposed on the side of the transparent protective layer 5 opposite to the solar panel 1; the anti-reflection structure 6 includes a plurality of periodically arranged first anti-reflection units 61 or a plurality of non-periodically arranged second anti-reflection units 62;

[0038] The second housing 2 includes a battery module 7, which is electrically connected to a solar panel 4, for use with glasses to be charged. Figure 3 (Not shown) is placed inside the second housing 2 to charge the glasses to be charged.

[0039] Specifically, the rechargeable eyeglass case provided in this embodiment includes a first housing 1 and a second housing 2. For example, the materials of the first housing 1 and the second housing 2 can be engineering plastic ABS (acrylonitrile-butadiene-styrene copolymer), aluminum alloy, etc. The first housing 1 and the second housing 2 are movably connected by a connecting part 3. For example, the connecting part 3 can be a metal hinge or a metal latch. The movable connection of the first housing 1 and the second housing 2 by the connecting part 3 allows the eyeglass case body to be freely opened and closed (in...). Figure 1 (The middle image shows the glasses case in the open position).

[0040] like Figure 3 As shown, Figure 3This is a schematic diagram of the glasses case in its closed state. A solar panel 4 is located on the side of the first housing 1 facing away from the second housing 2. The function of the solar panel 4 is to directly convert light energy into electrical energy to charge the glasses. A transparent protective layer 5 is provided on the side of the solar panel 4 facing away from the first housing 1 to protect the solar panel 4. An anti-reflective structure 6 is provided on the side of the transparent protective layer 5 facing away from the solar panel 4 (see reference). Figure 4 or Figure 5 The anti-reflective structure 6 includes a plurality of periodically arranged first anti-reflective units 61 (e.g., ...). Figure 4 As shown), or multiple second antireflective units 62 arranged non-periodically (e.g. Figure 5 (as shown);

Figure 4 and Figure 7 The duty cycle of the first antireflective unit 61 is 50%-95%. For example... Figure 7 It can be seen that the modulation effect is more obvious when the duty cycle of the first antireflection unit 61 is between 50% and 95%.

[0047] Optional, see reference Figure 5 The width of the second antireflection unit 62 is less than or equal to 5 μm, and the interval between any two second antireflection units 62 is 100 nm - 2 μm.

By setting the width and interval of the second antireflection unit 62, the processing accuracy requirement of the second antireflection unit 62 is minimized, which is conducive to reducing the difficulty of production and processing and improving the yield.
